Quick Answer
When breaking in a new barrel, it's generally recommended to shoot slower rather than faster, as this helps to prevent excessive wear and tear on the rifling and barrel chamber.
Initial Break-In Technique
When breaking in a new barrel, it’s essential to establish a consistent shooting routine. Start by firing a few rounds at a moderate pace, around 2-3 shots per minute, to give the barrel a chance to heat up and settle. This helps to expand the barrel’s chamber and smooth out any rough edges, which can be caused by machining or shipping.
Gradually Increasing the Pace
Once the barrel has had time to warm up, you can gradually increase the pace of your shooting. Aim for 5-7 shots per minute, taking care not to push the barrel too hard too quickly. It’s better to err on the side of caution and increase the pace gradually, rather than risking excessive wear and tear on the rifling.
Monitoring the Barrel’s Condition
As you continue to break in the barrel, pay close attention to its performance. Check for signs of excessive wear, such as increased muzzle rise or a decrease in accuracy. If you notice any of these issues, slow down your shooting pace and give the barrel more time to break in. A general rule of thumb is to shoot no more than 50 rounds per 100-degree temperature change, or 20 rounds per 50-degree temperature change. This helps to prevent thermal shock and maintain the barrel’s integrity.
